MOWlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 604,353, dated May 1'7,1898. Application filed November 26, 1897. Serial No. 659,792. (Ilomodel.)

and I do declare the following to be a full, clear, and exactdescription of the invention,-

such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompany-' ingdrawings, and to the letters and figures of reference marked thereon,which form a part of this specification.

This invention relates to new and useful improvements inmowing-machines.

The objects of the invention are to provide means for enabling thesickle-bar to be raised to any angle from the ground by the operatorwithout having to stopthe knife or throw the gearing out of mesh and toprovide means for driving the sickle truer than is possible by a pitmanand crank, thus doing away with the up-anddown movement.

Referring to the accompanying drawings, Figure 1 is a plan view of amowing-machine, showing in section the casing and a plan view of theinterior mechanism. Fig. 2 is an enlarged sectional side elevation ofthe casing inclosing the sickle-bar mechanism. Fig. 3 is a sideelevation of the inside casing. Fig. 4 is a side elevation of thesickle-bar connections. Fig. 5 is a similar view of the ballsocketpiece. Fig. 6 is a similar view of the rotating beam. Fig. 7 is asimilar view of the ball-and-pivot beam. Fig. 8 is a side elevation of amower having myinvention thereon.

Similar reference characters indicate the same parts in the severalviews.

1 is the outer case, hinged on the axle 2 and supported at its outer endby a brace-rod 3, which is bolted to said case.

5 is an inner case inclosed in case 1 and adapted to a rotary movementtherein, which movement is the same as that of the sicklebar 6. A pin 7extends from the outer end of case 5 and projects into an opening in theend of the arm 4,," and thereby the said case 5 is prevented from comingout of the outer case. The said arm and pin also prevent the outer endof the sickle-bar from getting out of line.

- oted ,to the inner end of the case 5 by a pin 12.

" 13 is a rotating rod or beam having its outer end bifurcated andpivoted to the arm 11, forming a'loose connection between the saidparts. The inner end of the rod 13 has a ball socket 14: to engage aball 15 on the crank 16, j forming a universal joint between the rod andcrank upon which the said rod turns. The

crank 16 is tight on a shaft 17, that has a bearing 18, which is part ofthe case, and said crank is driven by abevel-pinion 19 thereon, which inturn is driven by a larger bevelwheel 20, sleeved on the axle of themachine. The wheel 20 has a small spur-wheel 21, that meshes with alarger spur-wheel 22, and wheels 20 and 21 are driven thereby.spur-wheel 22 is fast on a shaft 23, and on the same shaft there is asmaller spur-wheel 24, which is driven by a similar wheel 25 on the mainaxle. The shaft 23 is adapted to be moved backward and forward in amanner that is common to mowing-machines, and the gearing may thus bethrown in or out of mesh. The detailed parts by which said shaft ismoved being old, it has not been deemed necessary to illustrate thesame.

26 is a connecting ball-socket link between the ball 10 on the arm 11and ball 27 on the sickle-bar 6, and thereby said sickle is driven.

29 is a hand-lever connected at 30 to aside of the outer case 1. Thislever is connected at its lower end by a link a to a pin 33, thatprojects inwardly from the shoe 32.

3e designates folding links having their lower end connected to said pin33 and upper end connected with a hand lever 35, fulcrumed on the sideof the case 1. The function of the lever 29 is to raise and lower thesickle-bar and that of the lever 35 is to tilt the said bar in awell-known manner. The link connections of the levers with the pin 33permit one lever to be operated without any interference from the other.The hand- The lever 36, fulcrumed on the draft-tongue 37, has aconnection with the opposite side'of the case 1.. This lever is to raiseand lower the case 1. When the gearing is in motion, a rotary motion isimparted to the rod 13, which transmits a reciprocating movement to thearm 11 and the sickle-bar irrespective of the position of the said bar.In elevating the sickle-bar this movement may continue uninterrupted. Inelevating the said sicklebar the inner case 5 also turns. The shoulder8, abutting with the outer end of the case 1, forms a bearing for thesaid case 5 to turn on and also prevents said case from entering theouter case 1.

The constructions described in the foregoing may also be used where itis not desired to operate the knife when the bar is raised by placingthe mechanism on the left side of the machine instead of the right sideand using a long pitman connection between the ball 10 and thesickle-bar and dispensing with the case 5, the tube 8, arms 8 andconnecting the sickle-shoe to the framework commonly used on longpitman-mowers.

Having described my invention, I claim 1. In a mowing-machine, thecombination with the casing l, of an inner casing 5 mounted to rotatetherein, a tubular case 8 mounted in the outer end of said case 5, thesaid tubular case 8 having a slot in the portion that is inclosed in thecase 5, a link 26 inclosed in the case 8, and having a ball-and-socketconnection with the sickle-bar, an arm 11 having a ball-and-socketconnection with said link 26, and a rotating beam to impart areciprocating movement to said arm, all arranged substantially as hereinshown and described.

2. In a mowing-machine, the combination with the case 1 mounted on theaxle of the machine, and a crank mounted in said case with gearing todrive it, of a case 5 loosely mounted in the outer end of said case 1, atube or case 8 mounted in the outer end of said case 5 and having anattachment with the shoe of the sickle-bar, an angular link 26 inclosedin said case 8 and having a univer- Sal-joint connection with thesickle-bar, a reciprocating arm 11 having a fulcrum in the case 5 and auniversal-joint connection with the link 26, a rotating beam 13 having apivotal connection with said arm 11, means for elevating the sickle-barwhile the same is in motion, substantially as shown and described.

3. In a mowing-machine, the combination with the case 1, of an innercase 5 rotatably mounted in the outer end of said case 1, a tubular caseS loosely mounted in the outer end of said case 5 in a transverseposition, the said case 8 having a slot in the portion that is inclosedin said case 5, and arms 8 adapted to be attached to the shoe of thesickle-bar, a reciprocating arm 11 having a fulcrum on the inner end ofthe case 5, and ball-and-socket connections between said arm and thesickle-bar, a rotating beam 13 having a flexible connection with saidarm 11, a crank havinga ball-and-socket connection with said beam, andmeans for driving said crank, and means for elevating the sickle-bar,substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
